Find the Root Cause. Heal Your Gut. Feel Like Yourself Again.
You’ve Been Told Your Labs Are “Normal” ..... But You Still Don’t Feel Like Yourself
Many people struggling with digestive symptoms, fatigue, hormone imbalances, skin issues, infertility, brain fog, or inflammation are told everything looks “fine” on standard testing.
But symptoms are signals.
At Gut Geeks, we take a deeper functional approach to help identify possible underlying contributors such as:
• Gut dysbiosis
• H. pylori
• Parasites
• Candida overgrowth
• Leaky gut / intestinal permeability
• Chronic inflammation
• Stress-related hormone imbalances
• Poor detoxification pathways
• Blood sugar dysfunction
• Nutrient deficiencies
Our goal is to help you better understand your body and create a personalized plan to support healing from the inside out.
Because Feeling Good Starts in Your Gut.
Find the Root Cause of Your Gut & Hormone Symptoms
Bloating. Fatigue. IBS. Food sensitivities. Hormone imbalances. Brain fog. Inflammation. Constipation. Skin issues.
These symptoms are often connected to underlying gut imbalances that conventional testing may overlook.
At Gut Geeks, we use advanced functional lab testing like the GI-MAP and DUTCH Complete to help uncover hidden infections, inflammation, dysbiosis, hormone imbalances, and stress-related dysfunction so you can finally understand what your body is trying to tell you.

"Working with Dr. Doug played an important role in helping me return to a high level of performance. In 2023, I was diagnosed with an autoimmune condition affecting my spine that significantly disrupted my ability to train and compete as a collegiate runner. After graduating, I returned to running recreationally while on a biologic medication, but I experienced side effects and later lost insurance coverage for the treatment in early 2025.After moving to Jacksonville, I scheduled a discovery appointment with Dr. Doug after learning about his work with athletes and complex recovery cases and his functional medicine informed approach. From the very first visit, Dr. Doug took the time to understand my full history and how my condition was impacting my training, recovery, and overall resilience. I appreciated his research informed, data driven approach and the way he explained everything clearly.As part of my care, Dr. Doug utilized functional medicine based diagnostics to help assess contributing factors and guide a more tailored, individualized plan. Rather than guessing or relying on one size fits all solutions, we used this information to support recovery and gradually rebuild my capacity to train.
Within a few months, I noticed meaningful improvements in my mental clarity, energy, and ability to tolerate consistent physical activity again. Over the following months, I continued progressing toward personal and athletic goals, including qualifying for the Ironman 70.3 World Championships and becoming a Pilates instructor.
I am very grateful for Dr. Doug’s guidance, communication, and performance focused approach throughout this process. If you are an athlete or active individual looking for a thoughtful, individualized approach to recovery and performance, I highly recommend Dr. Doug"

"Hi, I’m Randy, and I proudly served in the U.S. Navy for over 13 years. After leaving the service, I struggled with lower back discomfort, sinus issues, and sleep problems that were taking a toll on my work, my marriage, and my overall wellbeing.
When I returned home to Jacksonville and began working with Dr. Douglas Suffield, everything finally clicked. For the first time, I felt truly heard and understood.
Dr. Doug used functional medicine testing and a personalized, root-cause approach to explain what was contributing to my symptoms. He gave me a clear plan forward—one that actually made sense and felt tailored to me. Over time, my sleep improved, my energy returned, and I started to feel like myself again. The positive changes strengthened my marriage and restored the quality of life I had been missing for years.
I’m sharing my story because I want other veterans and first responders to know that real support exists. Dr. Doug’s dedication, insight, and compassion made a meaningful difference in my life, and I believe his approach can help many others find the same hope and direction."

Through functional medicine assessments, personalized nutrition support, and clear guidance, Dr. Doug helped me understand what was contributing to my symptoms and how to support my body in a healthier way.Over time, my sleep improved, my mental clarity increased, and my overall sense of wellbeing began to return. What I appreciated most was that I finally had a plan, support, and a practitioner who truly listened.
I am deeply grateful for Dr. Doug and his commitment to bringing education, support, and hope to the veteran community."
